One of the great side shows to the annual Pebble Beach concours on California’s Monterey Peninsula in August is the auctions. The big houses trot out some of the more interesting collector cars available in the world today and the high rollers of the collector world are there to scoop them up.

On August 16, Bonhams will be showing a myriad of delicious metal at the Quail Lodge in Carmel. Among them is one I find more delectable than much of the rest. Lot 139 is a 1961 Mercedes-Benz bus (model 0321H, for the Benz bus aficionados) and it was used by a Swiss hockey team to transport players to and from their games.

The bus has since been converted to a recreational vehicle, but mercifully still retains its original looks, with acres and acres of glass, including roof-mounted tinted windows. The thing must have been used as a tour bus at some point in its life. The specs: it has a 5.1-liter, 6-cylinder diesel engine with 110 horsepower (zero to 60 in less than one day) and a five-speed manual transmission. It’s not for everyone.
